In the summer,which is a rainy season,the water level of the impounding reservoir is higher than the Yangtse River,so we must pump the water with the municipal drainage pumping it isn’t pumped on time,it will result in delay of dealing with emergencies,serious hydrocele below traffic bridges and a lot of inconvenience of living and the rapid development of city construction,the scale of the municipal drainage pumping station is increasing the automatization of the whole control process through establishing the supervisory work of the drainage pump station is being more and more modified project of luojialu drainage pumping station is to substitute the manual control system to automation system. The research and application of the pumping station automatic monitor system will improve the degree of the control system,increase the reliability of the operation,decrease the intensity of the personal on duty and monitor the equipment status in realtime. Luojialu drainage pumping station automatic monitor system is posed of pumping station control system,central control system and munication PLC and relative modules collects the sample data and controls the equipments,and transmit the information to the central control system which implements remote control sends the control order to the pumping control system. The concern of this paper is discuss the development of the supervisory interface with simatic WinCC,which implenments the munication between the PLC and the supervisory puter and the supervisory interface.
